UV Editing - how?

[luckychris]

I could now successfully import my animation into Blender (thx for the very fast update of the Blender importer which works now perfect)

Thx to this hint:

if no material is added to a visual shape in Chrono, you can add by hand in Blender to 
#   the asset object available in "chrono_assets" collection. (link to data, not to object);
#   if a material is added to a visual shape in Chrono, it overrides the material you add to
#   the asset object available in "chrono_assets" collection (unless you disable "Chrono materials" in
#   the Chrono sidebar panel).

i could also change materials successfully.

But i couldn't find a way to UV unwrap my object. Do you have a documentation or a way to do that? Because just "normal" coloring of objects doesn't make realistic renders.

Thank you for any hint/help.
